TouchableOpacity not working inside an absolute positioned View

Just add zIndex : 1 to the view containing the buttons.

Also note: adding elevation adds shadow to android button and sometimes elevation may also be a issue if it's added to parent and not added to child then the child button may not work (Rare Case).

eg:

buttonContainers:
  {
    zIndex: 1,
    alignSelf: 'flex-end',
    position: 'absolute',
    top:5,
    right: 5,
    height: 40,
    borderWidth: 1,
    justifyContent: 'center',
    alignContent: 'center',
    width: 80
  },

Importing TouchableOpacity from "react-native-gesture-handler" worked for me

import { TouchableOpacity} from 'react-native-gesture-handler'

Even though the tab bar visually appears to be above the content in the list, the touch events for the list may be receiving it before the tab bar. Add a zIndex to the tab bar to allow it to receive touch events first.

Look at your import. If import { TouchableOpacity } from 'react-native-gesture-handler'; doesn't work, you need import this from 'react-native'.
